I'd be happy to explain what's being tested in the provided benchmark.

**Overview**

The benchmark compares the performance of two methods: `JSON.stringify` (from JavaScript's built-in JSON object) and `_isEqual` from the popular utility library Lodash. The test cases create two objects, `window.foo` and `window.bar`, with similar structure but different values, and then measures which method is faster in comparing these two objects.

**Options Compared**

The benchmark compares two methods:

1. **JSON.stringify**: This method converts a JavaScript object to a JSON string using the built-in `JSON.stringify()` function.
2. **_isEqual_ (Lodash)**: This method compares two values for equality, with options to customize the comparison logic. In this case, it's used to compare the two objects `window.foo` and `window.bar`.

**Pros and Cons**

Here are some pros and cons of each approach:

* **JSON.stringify**:
	+ Pros: Simple, built-in function, easy to understand.
	+ Cons: Can be slow for large objects due to the overhead of serializing and deserializing the data.
* **_isEqual_(Lodash)_**:
	+ Pros: Optimized implementation, can handle complex comparison logic, and is often faster than `JSON.stringify`.
	+ Cons: Requires an additional library dependency (Lodash), which may add overhead.

**Library and Features**

In this benchmark, Lodash is used to provide the `_isEqual` function. No other libraries or special JavaScript features are mentioned.

Now, let's analyze the results:

The latest benchmark result shows that:

* **_isEqual_(Lodash)_** is faster than `JSON.stringify` on Firefox 77.
* The performance difference is significant, with Lodash performing approximately 1.47 times better in terms of executions per second.

This suggests that when using Lodash's `_isEqual` function to compare objects, it can be a more efficient option compared to the built-in `JSON.stringify` method, especially on modern browsers like Firefox 77.
